I've converted quite a few of the DUBOIS AND MCNAMARA TRS-80 games to the run on the 'bee some years back. These are the steps I took -
1. Change ORG to 900h
2. Call 8027h (LORES) that sets up the TRS-80 graphics
3. Change all reference to TRS-80 screen mem ((3C00h-3FFFh) to F000h to F3FFh.
4. Change their SOUND code to suit the Microbee
5. Add a code routine to look for a key press and then change the code to use that routine. This is the hardest part I find.
Have a read of the porting_meteor_mission_2_to_microbee.pdf file by Brad Robinson. Its in the Microbee/Documentation/Articles folder in the Repository as it explains the whole process in detail.
